摘要
QZSS为与其他导航系统具有较好的兼容性,设计了与GPS、Galileo兼容的信号频率,因此分析QZSS对GPS、Galileo定位性能的影响非常重要。本文利用4个日本地区的IGS跟踪站实测数据,评估了QZSS的数据质量以及对GPS、Galileo伪距单点定位和精密单点定位的影响,发现QZSS数据质量良好,兼容频率对Galileo伪距单点定位精度的影响大于GPS,对GPS和Galileo精密单点定位精度的影响相当,但相比于GPS和Galileo单系统定位精度有了较大的提升。
In order to have better compatibility with other navigation systems,QZSS has designed signal frequencies compatible with GPS and Galileo.Therefore,it is very important to analyze the impact of QZSS on GPS and Galileo positioning performance.In this paper,the measured data from 4 IGS tracking stations in Japan were used to evaluate the quality of QZSS data and its impact on GPS and Galileo pseudo-range single-point positioning and precision single-point positioning.The impact of point positioning accuracy is greater than GPS,and the impact on GPS and Galileo precise single-point positioning accuracy is equivalent,but compared to GPS and Galileo single system positioning accuracy has been greatly improved.
